sydänlihassolua
Sydänlihassolu, also known as a cardiomyocyte, is a specialized muscle cell found in the heart. These cells are the fundamental building blocks of the myocardium, the muscular tissue that makes up the heart wall. Cardiomyocytes are responsible for the heart's ability to contract and pump blood throughout the body.
Structurally, cardiomyocytes are distinct from skeletal muscle cells and smooth muscle cells. They are typically uninucleated
The cytoplasm of a cardiomyocyte is packed with myofibrils, which are composed of actin and myosin filaments.
The electrical activity of cardiomyocytes is crucial for maintaining a regular heartbeat. They possess automaticity, the
